CBN Tightens Payment Rules to Reduce Risk in Nigeria’s Fintech Ecosystem

The Central Bank of Nigeria has introduced new rules to strengthen the country’s fast-growing payments ecosystem.

The rules target competition, ownership transparency, payment data storage and systemic risk across Nigeria’s digital finance market. The CBN addressed the circular to banks, microfinance banks, mobile money operators, switching companies, payment terminal service providers, payment solution service providers, super agents and other licensed payment operators.

The move shows that the regulator wants tighter control over a sector that now sits at the centre of banking, commerce, mobile money and everyday transactions.

Why the CBN Is Acting Now

Nigeria’s electronic payments market has expanded quickly.

More people now use mobile apps, cards, bank transfers, point-of-sale terminals and digital wallets for daily payments. This growth has improved financial inclusion and created new business opportunities.

But it has also created new risks.

The CBN said the expansion of electronic payments and digital financial services has raised concerns around market concentration, operational dependence, systemic risks, ownership transparency and the location of critical payment data.

That statement explains the regulator’s main concern. Nigeria’s payment system has become too important to run with loose visibility.

New Ownership Disclosure Rules

The CBN now wants payment operators and financial institutions to show who truly owns or controls them.

Under the new framework, deposit money banks, payment service providers and other financial institutions with digital payment operations must disclose the ultimate beneficial ownership of major shareholders. They must do this in line with existing anti-money laundering, counter-terrorism financing and counter-proliferation financing rules.

Institutions must also keep accurate ownership records and provide them to the CBN when requested.

This rule matters because opaque ownership can create regulatory blind spots. It can also weaken investor confidence and expose the system to illicit finance risks.

Payment Data Must Stay in Nigeria

The new circular also introduces a major data localisation requirement.

The CBN says payment transaction data generated in Nigeria must remain stored and managed within the country. The regulator also expects affected institutions to comply with Nigerian data protection laws and regulations.

Payment operators must fully comply with the data localisation rule by January 1, 2027.

This requirement could reshape how fintechs, banks and payment processors manage cloud infrastructure. Companies that store or process data outside Nigeria may need to review their technology systems, vendor contracts and compliance models.

It could also push more investment into local data centres and domestic technology infrastructure.

CBN Moves Against Market Concentration

The CBN also wants to reduce concentration risk in card issuing and merchant acquiring.

Under the new rules, any licensed financial institution with more than 25% of the card-issuing market over a rolling 12-month period cannot hold more than 15% of the merchant-acquiring market during the same period.

The rule also works in reverse. Institutions with more than 25% of the merchant-acquiring market cannot hold more than 15% of the card-issuing market.

This is one of the most important parts of the circular.

The CBN wants to stop a few dominant players from controlling too many layers of the payment value chain. In simple terms, the regulator does not want the same company to dominate both card issuing and merchant acquiring at the same time.

Monthly Market Share Returns Now Required

The CBN also directed affected institutions to submit monthly market share returns using prescribed reporting templates.

The regulator expects full compliance with this reporting requirement by December 31, 2026.

This will give the CBN better market visibility. It will also help the regulator track dominance, detect concentration early and intervene before a major operator becomes too systemically important.

What This Means for Banks and Fintechs

Banks and fintechs now face a heavier compliance burden.

They must review their ownership records, payment data architecture, market share position and reporting systems. Firms with strong compliance teams may adjust quickly. Smaller operators may need more investment in legal, risk, technology and governance functions.

The data localisation rule may create the biggest operational challenge. Payment companies must confirm where transaction data sits, who manages it and whether their cloud providers meet Nigeria’s regulatory expectations.

Market leaders may also need to review their business models if they hold strong positions across card issuing and merchant acquiring.

Expert View

The CBN’s new rules show that Nigeria’s payments industry has entered a more mature phase.

The regulator no longer sees digital payments as only an innovation story. It now sees the sector as critical financial infrastructure.

That shift makes sense. Payment companies handle sensitive data, process huge transaction volumes and connect banks, merchants and consumers. If one dominant operator fails, the impact can spread across the economy.

The new framework may raise costs for operators in the short term. But it could also improve trust, competition and investor confidence over time.

The biggest challenge will come from implementation. The CBN must enforce the rules without slowing innovation or pushing smaller fintechs out of the market.

Final Take

The CBN’s new payment rules send a clear message to Nigeria’s financial technology sector.

Growth is no longer enough. Payment operators must now prove that they can grow with transparency, resilience and stronger governance.

For consumers, the rules could support safer digital transactions. For fintechs and banks, they create a new compliance test.

For the wider economy, the circular marks a deeper regulatory push into one of Nigeria’s most important digital sectors.
